Hydrogen production via glycerol dry reforming over nickel catalyst supported on sio2 and Al2O3 modified by La
Currently, energy has become the most demand for human needed. The utilization of future energy that is clean and sustainable becomes increasingly urgent because of dwindling petroleum reserves and mounting environmental concerns that are associated with fossil fuel. Hydrogen has been considered as...

Currently, energy has become the most demand for human needed. The utilization of future energy that is clean and sustainable becomes increasingly urgent because of dwindling petroleum reserves and mounting environmental concerns that are associated with fossil fuel. Hydrogen has been considered as the most suitable alternative for future energy aiming to reduce the dependence on fossil fuel and carbon based emission. Previously, non-renewable resources mainly coal, fossil fuel, petroleum coke, and petroleum residues has been widely used as the main feedstock for syngas (H2 and CO) production. However, due to the various factors such are global warming, the unstable price and availability of petroleum-based oil as well as the environmental pollution, the desirability towards biomass (glycerol) as the alternative energy feedstock has attract the world’s attention. Glycerol which a by-product of biodiesel production is one of the most promising renewable sources associated environmental impacts from the usage of the fossil fuels in which it minimal carbon dioxide (CO2) emission and more preferable in fuels production. In recent years, the production of hydrogen from glycerol via steam reforming widely investigated, only a few studies on dry reforming with CO2.
